Building and using Fledge on Raspbian¶
Fledge requires the use of Python 3.5.3+ in order to support the asynchronous IO mechanisms used by Fledge. Earlier Raspberry Pi Raspbian distributions support Python 3.4 as the latest version of Python. In order to build and run Fledge on Raspbian the version of Python must be updated manually if your distribution has an older version.
NOTE: These steps must be executed in addition to what is described in the README file when you install Fledge on Raspbian.
Check your Python version by running the command
If your version is less than 3.5.3 then follow the instructions below to update your Python version.
Install and update the build tools required for Python to be built
sudo apt-get update sudo apt-get install build-essential tk-dev sudo apt-get install libncurses5-dev libncursesw5-dev libreadline6-dev sudo apt-get install libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev sudo apt-get install libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev
Now build and install the new version of Python
wget https://www.python.org/ftp/python/3.5.3/Python-3.5.3.tgz tar zxvf Python-3.5.3.tgz cd Python-3.5.3 ./configure make sudo make install
Confirm the Python version
python3 --version pip3 --version
These should both return a version number as 3.5.3+, if not then check which python3 and pip3 you are running and replace these with the newly built versions. This may be caused by the newly built version being installed in /usr/local/bin and the existing python3 and pip3 being in /usr/bin. If this is the case then remove the /usr/bin versions
sudo rm /usr/bin/python3 /usr/bin/pip3
You may also link tothe new version if you wish
sudo ln -s /usr/bin/python3 /usr/local/bin/python3 sudo ln -s /usr/bin/pip3 /usr/local/bin/pip3
Once python3.5 has been installed you may follow the instructions in the README file to build, install and run Fledge on Raspberry Pi using the Raspbian distribution.
